Patent EP-0383387-A1 (EP)
Inventor: BOUDEWIJNS ARNOLDUS JOHANNES J
IPC: H01L21/339
Filed: 1990-02-09
Abstract: A delay line, especially for delaying t.v. signals, comprising a series of signal storage capacitances, an input line, an output line, selection transistors between the storage capacitances and the input and output lines and a digital shift register for activating the selection transistors. According to the invention, the output line comprises a central part, on either side of which signal storage capacitances with associated selection transistors are located, which in turn are located between the central part of the output line and the associated parts of the shift register. The design according to the invention results in a compact configuration, which moreover has the advantage that the parasitic capacitance of the output line is comparatively low. The configuration can be readily extended to two interlaced delay lines having a single common shift register.

Abstract: In a conveyor means (22, 26, 24) for conveying materials, a flow metering device (26) for metering the weight rate of a materials flow, comprises rotatable impeller means (42/60, 62/88) which are mounted on a drive shaft (32) and are operable to propel the materials. The impeller means (42/60, 62/88), when conveying materials, are subjected to forces which are directed generally perpendicular to the materials engaging surface of said impeller means (42/60, 62/88). 
     The impeller means (42/60, 62/88) are movable relative to the drive shaft (32) and homing means (- /96) are provided which, in use, tend to position the impeller means (42/60, 62/88) in a home position corresponding to the idle running condition of the flow metering device (26) and which, when materials are being conveyed, permit said generally perpendicular forces to displace said impeller means (42/ 60, 62/88) opposite to the action of the homing means (-/96). The amount of displacement is indicative of the weight rate of the materials flow.

Abstract: It is difficult to store and aspirate liquids in reduced gravity environments without contaminating the immediate environment. Described herein is a container (10A) and a method for aspirating liquids stored in such a container (10A). The container (10A) includes a plurality of flexible columns (40A) which project from a wall surface (26A, 36A) of the container (10A) which allow controlled capillary attraction to hold the liquid in place for storage. However, the capillary attraction is not so strong that the liquid cannot be aspirated away. The controlled capillary attraction is such that a column of water which is between about 2mm and about 60mm in height is supported by the columns (40A). Other materials, for example, foam or fibers, are also useful for storing liquids prior to aspiration.

Abstract: A clean pitch suitable for the manufacture of carbon artifacts is obtained by distilling from an aromatic feedstock a distillate material free from mesophase and mesophase forming resins. The distillate is heated to obtain a heat soaked distillate free from mesophase but containing mesophase forming resins. The heat soaked distillate is further heated with inert gas sparging to convert it to mesophase pitch suitable for manufacturing carbon fibers. The heat soaked distillate also finds use as a binder or impregnation pitch.

Abstract: An automated workpiece handling system rapidly moves a workpiece (127) into a controlled atmosphere chamber (11) such as a vacuum chamber, to a work station and withdraws the piece (127) after the work has been completed. While at the work station, the handling system manipulates the piece (127) linearly and in rotation, as desired, according to a set program. The workpiece (127) is loaded and unloaded at the same location outside the chamber (11), at atmosphere pressure. A split piston having a headstock (49) and tailstock (50) holds the workpiece (127). The piston seals the vacuum chamber (11) during loading and unloading, and during the work cycle. During transfer into the vacuum chamber (11), pressure around the workpiece is reduced. A pneumatic counterbalance system (111,143,141,109) reduces the loading on the piston drive system caused by the pressure differential between the vacuum chamber (11) and atmosphere.

One form of improved seal includes a sealing ring (52) having a tubular body with an external flange or hub (56) to be clamped between the joint surfaces of the joint members, tapered external surfaces (58, 60) which mate with and provide a tight sealing engagement with the tapered surfaces (34, 48) of the joint members and tubular rims (62, 64) extending away from the tapered surfaces and having sufficient length to protect the straight cylindrical sealing surfaces (38, 50) of the joint members. A modified form of improved seal includes a sealing ring having a tubular body with an external flange to be clamped between the joint surfaces of the joint members, and tubular rims terminating in an external rounded portion having a short annular flat sealing surface thereon for engaging the straight cylindrical sealing surfaces of the joint members at a position spaced axially from the tapered sealing surfaces of the joint memebers.

Abstract: A self cleaning flow control orifice mounted in an exhaust line. A toroid having a rounded inner surface is mounted in the exhaust line and forms an orifice. A cleaning device is mounted in a manner to provide close contact between the cleaning device and the rounded surface. The toroid and cleaning device are rotated relative to one another so that the cleaning device rides over the rounded surface to clean the surface. The clean surface thereby insures proper functioning of the exhaust system of an atmospheric pressure chemical vapor deposition apparatus used to deposit films on substrates and wafers.

The belt (27) is supported by freely rotatable rollers (28,29) which are mounted on a slidable carriage (31) which is movable along in the direction of the adhesive tape path through the printer. The movement of the carriage (31) adjusts the length of the adhesive tape path between the printer (18) and the tie forming mechanism to vary the location of the printing on the completed adhesive tape ties.

Abstract: Est décrit un procédé pour l'assemblage d'un maître cylindre tandem et d'un servofrein à dépression d'un circuit de freinage hydraulique pour véhicules à moteur. De l'air est injecté par l'intermédiaire des raccords de pression (19, 36) des chambres de pression (11, 18) associées aux pistons (2, 3). Simultanément, les pistons (2, 3) sont déplacés dans le sens de la pédale de frein. Tandis que les pistons (2, 3), et donc également la soupape centrale (14) logée dans le piston flottant (3), se déplacent, l'accroissement de pression dans la chambre de pression (18) est mesurée. Dès que l'élément de fermeture (15) de la soupape centrale (14) repose sur le siège de soupape (16), et qu'ainsi la soupape centrale est fermée, la pression d'air dans la chambre (18) augmente. Sur la courbe indiquant l'augmentation de pression dans le diagramme ''pression/course de la soupape centrale'', est défini un point de déclenchement qui détermine une distance de mesure sur l'abscisse du diagramme. Cette distance de mesure détermine le nombre et/ou le dimensionnement de rondelles d'écartement (8) disposées enttre l'élément de pression (9) et le piston (2) de la tige de compression afin de réduire la course morte de la soupape centrale (14). L'invention représente ainsi un procédé élégant, se prêtant à l'automatisation, pour l'assemblage d'un maître cylindre tandem et d'un servofrein à dépression et pour une réduction simultanée de la course morte de la deuxième soupape centrale (14).
